Bug#5379: ispell bug 5379

[David Coe <david.coe@someotherplace.org>]

I've extracted the following from a recent email conversation
I had with Geoff Kuenning, the upstream author/maintainer:

> ...munchlist.X contains this comment, which may be relevant:> 
>
> #       -w      Passed on to ispell (specify chars that are part of a word)
> #               Unfortunately, special characters must be quoted twice
> #               rather than once when invoking this script.  Also, since

> #               step ignores it, making it somewhat less than useful.

I've done a bit of investigation since your last mail.  It turns out
that the problem is caused by icombine, which doesn't support the -w
switch.  Adding support, and modifying munchlist to pass the switch to
icombine, isn't very hard.  At the same time, I can fix buildhash to
take the same switch so that it'll work properly throughout.
